Retinal Detachment
Conditions
Brief summary
The study is collecting data along with other academic institutions regarding the accuracy of ocular ultrasound in diagnosing retinal detachment.
Detailed description
This is a prospective, cross-sectional study to assess the utility of point of care ultrasound in the diagnosis of ocular complaints in the emergency department (ED) with specific focus on the accuracy of diagnosis when compared to that of a blinded ophthalmologist. Ocular complaints represent between 2% and 3% of ED visits (Walker et al, 2011). This percentage may include vision-threatening diagnoses including retinal detachment, which can occur in 3-4% of patients presenting with ocular complaints (Alotaibi et al, 2011). However, the equipment and expertise required to adequately assess for conditions such as retinal detachment are limited in busy emergency departments due to the time consuming and challenging nature of the examination. Incorporating the use of an ultrasound could provide a more available, focused, and timely assessment.
Interventions
DEVICEUltrasound
Each participant will receive an ocular ultrasound which poses minimal to no harm to the participant and the ultrasound results compared to final diagnosis.
OTHEROphthalmology Assessment
Number of subjects with retinal detachment per formal ophthalmology assessment. This assessment is a composite measurement which includes the following chief complain, primary impression, right visual acuity, left visual, acuity, ultrasound diagnosis, diagnosis changed, ophthalmology diagnosis.

| Patients Receiving Ultrasound Enrolled participants will receive a bedside ocular ultrasound of the affected eye and the ultrasound will be compared with the ophthalmologist diagnosis. The participant's medical record will also be reviewed for information regarding demographics, complications, and outcomes.
Ultrasound: Each participant will receive an ocular ultrasound which poses minimal to no harm to the participant and the ultrasound results compared to final diagnosis. | 5 |
